Welcome aboard Matt. Glad you are enjoying your F30. Yep, some problems can be so very hard to solve. I haven't travelled terribly far in my car but to date, I have not experienced the issues you are having.
First thing is to email your dealer with your complaint and even the complaint from jan999 as reference. You could follow up with a call but keep all correspondences in writing until satisfactory resolution. Please keep us informed.
Enjoy the toy.
